High resolution observations of a very quiet region of the solar surface have been obtained with IBIS (Interferometric BIdimensional Spectrometer) in the non-magnetic Fe I 7090.4 Å spectral line. We present a first comparison between the observed, spatially resolved, spectral data and the simulated spectra in a 3D snapshot of a radiation

On July 4 2005 the NASA spacecraft Deep Impact delivered an impactor on the comet 9P Tempel 1 to study the material underneath the surface of the nucleus A worldwide observation campaign accompanied the mission to characterize the activity of Tempel 1 before and after the impact At La Palma Canary Islands the comet was observed from July 2 to July

HST multi-epoch images and VLT integral-field, high resolution spectroscopy allowed us a robust determination of the 3-D geometry and orientation of the nebula surrounding He 2-147, and to measure its apparent expansion in the plane of the sky. Applying the expansion parallax method results in a distance which is significantly shorter that the one
